Question

I’ve seen a few different posts on this, but I can’t seem to get it working. I basically have a UITableView and want sort buttons at the top of a popover controller. I followed this post: UIPopoverController toolbar at top in order to get started. In my controller that is the rootViewController of the navigationController, I can create a UISegmentControl and place it at the top. However, it does not look like the picture in that it’s not centered. Maybe because the way I get it into the popover is in the viewDidLoad of the popover like this:

   UISegmentedControl *topSegmentControl = [[UISegmentedControl alloc] initWithItems:[NSArray arrayWithObjects:@"One", @"Two", @"Three", @"Four", nil]];
    topSegmentControl.backgroundColor = [UIColor clearColor];
    topSegmentControl.segmentedControlStyle = UISegmentedControlStyleBar;
    UIBarButtonItem *toolBarCustom = [[UIBarButtonItem alloc] initWithCustomView:topSegmentControl];
//    UIBarButtonItem *spaceItem = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemFlexibleSpace target:nil action:nil];
    self.navigationItem.leftBarButtonItem = toolBarCustom;

Also, if I want to present data at the bottom of the popovercontroller in a toolbar, I’m not sure where to do that. Following the same example: UIPopoverController toolbar at top, I thought in my navigationController, I would do something like this:

 UISegmentedControl *topSegmentControl = [[UISegmentedControl alloc] initWithItems:[NSArray arrayWithObjects:@"BottomOne", @"BottomTwo", @"BottomThree", nil]];
//    topSegmentControl.backgroundColor = [UIColor clearColor];
    topSegmentControl.segmentedControlStyle = UISegmentedControlStyleBar;
    UIBarButtonItem *toolBarCustom = [[UIBarButtonItem alloc] initWithCustomView:topSegmentControl];
    UIBarButtonItem *spaceItem = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemFlexibleSpace target:nil action:nil];
    NSArray *array = [NSArray arrayWithObjects:spaceItem, toolBarCustom, spaceItem, nil];
    [navController setToolbarItems:toolBarCustom];
    [navController setToolbarHidden:NO];

When I try this, I see a toolBar with nothing in it, that is a lighter tint than the rest of the popover.

To summarize, I’m not sure as to where you would initialize toolbar or barbuttonitems for a popover that has a navigationcontroller like in the example. I’m also not sure how to center the data. Thanks.

You’ll probably be best suited by just setting your UISegmentedControl as the titleView of your root view controller’s navigationItem.
